Slapped the mufflers on. Copper RTV on the bolt threads and a thin coat on the muffler mating surfaces.

I do my exhaust the same way. Never had one come loose.

I tried to fit nordlocks as well, but they are wider than the hole. I really am a big fan of this method as well.

Do you let the RTV dry before you mount the muffler.

Not really... I tightened the bolts until they just started to squeeze out some RTV, waited a little bit then tightened them all the way. I think tightening them all the way in the beginning is the way to go, thinking that if there was any give in the RTV, it would eventually break down and get loose... Just my thoughts, not experience.

Worked on my choke setup. Basically found a threaded pushrod I had laying around, put a 2-56 ball link on it. Drilled a hole where I could dangle a piece of wire with a z bend in it attached to the choke lever. Put the cowl on, and checked where it hit and marked and dremeled out a hole large enough for a small grommet. Put on my linkage setup, let it protrude out the exit, made some strategic bends, trimmed it and created a flat spot and installed a wheel collar.

Which throttle servo did u end up going with?
Build looks awesome! Extremely impressed with airframe quality.

Next job indeed! Fine tuning surfaces to match each other. Setting EPAs and deflections.
The miracle throw meters are nice, you have to be gentle because there centering is picky, need to make a fixture that opens the jaws up a little. But works for now. Used a little digital protractor to match each side easier.
40deg ailerons
55deg elevators
50deg rudder (I know it says 45... changed it to 50 for now)

I’m using the 1267. If it does fail, it would just stick for a second based on what I’ve seen.... but it has worked well for others and it’s super popular so we shall see!
